Application filed J 'anuary 17, 1914. Serial No. 812,774.

To (ZZZ whom it may concern Be it known that I, ALFRED ORTON, a citizen of the United States, residing at Cheyenne, in the county of Laramie and State of lVyoming, have invented a new and usefulv Jig Attachment for Planers, of which the following is a specification.

The present invention appertains generally to metal planers, and relates more particularly to a jig or templet attachment therefor. I g

It is the object of the present invention to provide a novel and improved jig for holding the pedestal shoes and wedges of locomotive driving boxes, whereby their faces may be conveniently and ehiciently planed.

Another obj ect' of the present invention is to provide device of the nature indicated which will be attachable tothe bed ortable of various planers, and which will be pro- }vided with means for properly setting it with respect to the planer bed or table, so that the pedestal shoe or wedge may be properly planed.

A further object of the present invention is to provide a device of the character specified which will conveniently accommodate various styles and sizes of pedestal shoes and wedges, and which shall be adjustable to accommodate shoes. l

A still further object of the present-invention is to provide a novel apron or guard carried by the body of the jig, and which is adapted to cooperate with the planer bed or table, to prevent chips or other foreign objects from passing between the jig body and the planer bed or table.

lVith the foregoing general objects out lined, and with other'objects in view, which will be apparent asthe nature of the invention is better understood, the present invention resides in the combination. and arrangement of parts and inthe details of construction hereinafter described and claimed, it being understood that changes in the 'precise embodiment of theinvention herein disclosed, can be made .within the scope'ofwhat is claimed, without departing. from the spirit of the invention. s I l The present invention hasbeen illustrated in its preferred embodiment in the accompanying drawings, wherein Figure 1 is a plan View of the improved Specification of Letters Patent.

Fig. 4 is an enlarged sectional detail of one of the contrivances for adjusting the jig body, the section being takenon the line .l lof Fig. l. Fig. 5 is a. fragmental bottom view of one corner of the jig body, illustrating the device depicted in Fig. 4:. Fig. 6 is a sectional detail illustrating the adjustable apron.

In carrying out the present invention, reference being had in detail to the drawngs, there is provided a body 1, preferably in the form of a suitable casting, and approximately rectangularin contour. This body 1 is of the proper size or proportions, so as to accommodate the pedestal shoes and wedges as will hereinafter appear. The body 1 is provided with a depending'longitudinal tongue 2 along its longitudinal median plane, which tongue is adapted toengagethe groove or a planer bed or table, to hold the body in position upona planer bed ortable, as will be apparent. The ends of the body 1 have slots 1 for the passage of bolts or other fastening devices to engage the planer bed or table. Y

" The. top or upper side of the body 1 is provided with "an upstanding longitudinal longitudinal median jaw 3 adjoining? the line of the body. To one side of the jaw 3, the upper face of the bodyis provided with a depression or cut away portionet extendof the body, ;the ing preferably co -extensive, and terminating short of the ends of the body. j .Disposed in. the depression or cut away portionl, is a plate orslide 5', which is preferably flush with the top of the body, and which has an upstanding jaw 6 along its inner edge coiip'erating with the jaw 3. The

plate or slide 5 and its jaw 6 are co-extensive with the jaw 3, the jaw 3 being pref? erably relatively wide,: while the jaw 6 is relatively thin or narrow.

The plate or slide 5 and the body 1 are provided with the upstanding ribs or flanges 7 and 8, respectively,

ingfromthe jaw 3 to therespective edge depression-it and jaw 3 beparallel with the jaws and disposed at the remote sides of the jaws and adjacent the respective side edges of the body. The flanges or ribs 8 each carry a series of jam orclamping bolts 9 which are directedxtoward the respective jaws.

l the plate or slide 5,

The upper portions of the jaws 3 and 6 are cut-awayintermediate their ends, to provide the inclined depressions 10' to accommodate the pedestal wedges, 'as hereinafter described, and adjoining the shoulders formed by the depressions 10, the jaws are provided with jaw 3- is provided with vertical bores or holes 12 adjoining the respective stop 11, and the lower ends of these bores 12 are directed out through the sides of the jaw 3,

as clearly seen in Fig. 3.

, The plate or slide 5 is adapted to be ad justed laterally within the depression 1, to move the jaw 6 toand from the jaw 3, and to this end, the body 1 is formed with T- slots. 13 at the bottom of the depression 4: and eXt'endilig inwardly from the respective edge of the body, as clearly seen in Fig. 3. Draft or clamping bolts 141 are carried by and have nuts 15 threaded on their upper ends and bearing against the top of the slide 5, while the heads 16 of the bolts engage under the shoulders of the slots or grooves 13. When the bolts 14 are loosened, it willbe evident that the slide 5 may be adjusted as desired, and that when the bolts are tightened, through the medium of the nuts 15, the plate or slide will be securely clamped within the depression 4 of the body. The slide 5 may be removed or detached from the body by disengaging the headed ends of the bolts 1A from the body, as will be obvious.

A guide plate 17 extends around the sides and ends of the body 1, the upper edge of the plate 17 being secured in any suitable manner to the body, in order that the plate 17 will depend over the respective sides and ends of thebody, The plate17 is cut away to accommodate the slide 5, and is also provided with the T-slots or openings 18 registering with the similar slots or grooves 13 of the body, in order to permit the bolts 1A to be engaged with and disengaged from the body. v

A sheet metal apron 19 is snugly disposed between the plate 17 and the body 1, so as .to slide or reciprocate vertically, the upper edge of the apron 19 terminating short of the upper edge of the guide plate 17. The apron 19 is also provided with upwardly opening slots or recesses 20 registering with the slots 18 and 13, to permit of the introduction'and withdrawal of the bolts 1 1, as above intimated. The apron 19 is spring pressed downwardly so as to seat upon the planer bed or table. To this end, coiled wire springs21 are seated within sockets or depressions 22 in the sides and ends of the body 1, and engage the upper portion of the apron 19 to yieldingly depress the apron. The upper edge of the apron 19 is preferably provided with instruck ears 23 workthe upper stops 11. The.

ing within the depressions 22, and against which the springs seat, to force the apron downwardly, although other means may be provided. for spring pressing the apron.

It is preferable to provide closure strips 21 adapted to be inserted between the guide plate 17 and the apron 19, to close the slots or openings 18 and 20, for preventing chips or other extraneous matter from entering the slots or grooves 13 of the body. These members 2 L may be readily inserted and withdrawn, as necessary.

The four corners of the body 1 are each provided with means for setting or truing the body 1 upon the planer bed or table, and inasmuch as the said means are duplicates of one another, only one need be de scribed in detail.

Each corner of the body 1 is provided with an upright bore or opening 25, the

upper end of which is contracted or reduced in diameter, as at 26, and that portion of the bore next inside or adjoining the reduced portion 26, is hexagonal or non-circular in cross section, as at 27. Diametrically opposed longitudinal channels 28 are provided adjoining the lower end of the bore or opening 25, the channels 28 extending from the bottom of the body to a point short of the contracted or reduced portion 26. A bushing or collar 29 is inserted upwardly through the bore 25 within the con.- tracted or. reduced portion 26, and is provided at its lower end with an enlarged portion or head 30 of hexagonal contour fitting snugly within the portion 27 of the bore and seating against a shoulder 31 provided by the portion 27 and contracted portion 26. The upper end of the collar 29 projects above the top of the body, and a binding nut 32 is threaded onto the upper end of the bushing or collar 29 and bears against the top of the body to clamp the bushing or collar tightly in position. A foot 33 of noncircular cross section is slidable within the lower end of bore 25, and has the diametrically opposite lugs 34: at its upper end engaging within the respective channels 28, plug screws 35 being threaded into the outer ends of the channels 28 to limit the outward movement of the lugs 34:: to thereby retain the foot 33 in engagement with the body. The lugs 3 1 are adapted to slide within the channels 28 and'to correspondingly permit the foot to slide, whereby the foot may be projected and retracted relative to the bottom of the body. A jam bolt 36 is threaded through thecollar or bushing 29and has its tip rounded and engaging a rounded socket or depression formed in the top of the foot 33, whereby the foot 33 may be depressed through the medium of the jam bolt 36. A coiled wire spring 37 is interposed between the collar 29 and the foot 33,-around wedge, so as to internally to y-ieldingly depress the boxes, such shoes and wedges being of channel-shaped cross section.

In practice, the body 1 is bolted orfastened on the planerbed or table, with the tongue 2 engaged into a "groove of the planer bed or table, wherebythe-body may be held above the same. When the body is thus applied to the planer bed or table, it will be evident that the apron 19 will be depressed against the planer bed or table to close the gap between the sides and ends of the body 1 and the planer bed,in order to prevent chips or other foreign matter from working underneath the body 1;. The pedestal shoe or wedge to be planed is then set astride the jaws 3 and 6 with its flanges disposed over the remote sides of the jaws within the ribs or flanges 7 and 8. The slide 5 is then. adjusted outwardly, in order to open the jaws between the flanges of the pedestal shoe or grip the pedestal shoe or wedge, and after the slide .5 has been properly adjusted, the same is clamped in position by the'bolts 14. The jam bolts 9 are then threaded inwardly to clamp the flanges of the pedestal shoe or wedge against the jaws, in which event the pedestal shoe or wedge will be rigidly held or clamped upon the body, with its face exposed.

In planing the faces of pedestal shoes or wedges, considerable care is necessary in properly adapting the shoes or wedges to the pedestal. or frame. plished by properly setting the body 1 in order that the face of the pedestal shoe or wedge may be properly planed when the planer table or bed is moved under the milling cutter or the like. The body 1 may be conveniently set by properly adjusting the jam bolts 36 at the various corners, it being noted that the spring 37 will ordinarily press the feet 33 against the planer bed or table. By threading the bolts 36 downwardly, the body 1 may be tilted slightlyin various directions so as to properly position the pedestal shoe or wedge.

The depression 10 of the jaws are designed to accommodate the pedestal wedges, as will be evident to those versed in the art, and the stops 11 are adapted to limit the movement of the pedestal shoes and wedges toward the respective end of the, jaws. The bores or channels 12- are adapted to conduct chips or other foreign material downwardly away from the stop 11 of the jaw 3.
